Yeah, typical serial number, bore and Louis Kelber's initials on the bottom of the lower tube. The remainder of the marks will be under the wood. But the possibility exists that the lower rung Merkel offerings were brought to an "in the white" state in St. Étienne / Loire and sent directly to the Suhl proof facility, then badged and completed in Suhl. I would say that Gebrüder Merkel was getting much more than just money for granting a license to a French manufacturing concern. I just don't remember that many Böhler steel tubes on St. Étienne wares.
